Application filed June Z, 1918. Serial No. 238,702.

and it consists in the novel features hereinafter described and claimed.

An object of the inventlon is to provide a razor of the character statedwhich is simple and durable in structure, embracing a minimum number ofparts and havlng the parts so assembled that they. may be readilydisconnected from each other for cleansing, sharpening the blades orpacking in compact space.

A. further object of the invention is to provide in a razor of thecharacter stated means whereby the handle may be positioned at a desiredangle with relation to the plane in which the blade of the razor lies,consequently the razor may be convenlently used over the face or anypart of the body.

A further object of the invention is to provide means for holding theblade during the stropping or sharpening of the same.

In the accompanying drawing Figure 1 is an edge view of the razor.

Figure 2 is a side View of the same.

Figure 3 is a plan view of the blade of the razor.

Figure 1 is a plan view of one guard plate of the razor.

Figure 5 is a similar view of the other guard plate of the razor.

Figure 6 is a side view of a stud used in the razor.

Figure 7 is a side view of the handle of the razor with parts shown inSBCtIOII.

Figure 8 is a side view showing the parts arranged for holding the bladefor stropping or sharpening.

Figure 9 is a perspective view of the blade holder.

Figure 10 is a transverse sectional view of the device cut on the line10--10 of Figure 8.

provided at, its center with a longitudinally (llS osed slot 2. a

guard plate 3 is adapted to be positioned at the outer side of the bladeand is provided wlth arched portions 4 adapted to )ass through the slot2 of the blade 1. he inner ends of the arched portions are separated orspaced by an opening 5. The razor further includes a guard plate 6 whichis provided at its opposite edges with the usual teeth 7. The plate 6 isfurther provlded at its center with a longitudinally disposed slot 8which is adapted to register with the slot 2 of the blade 1 and isadapted to receive the arched portions 4 of the blade 3 when the partsare assembled. The plate 6 is further provided at a point between theends of the slots 8 with a hump 9 which bridges the slot 8. The saidhump 1s substantially convexo-concaved in configuration and is providedwith a slot 10 having its median longitudinal dimension disposed at aright angle to the corresponding dimension of the slot 8.

The razor further includes a T-shaped stud 11 which is provided with asubstantially cylindrical head 12. The head 12 is adapted to lie withinthe arched portion 4 of the plate 3 and the shank of the stud 11 passesthrough the opening 5 and the slots 8 and 10. A handle 13 is rovided atone end with a threaded socket it which is adapted to be screwed intoengagement with the shank or stem of the head 11. Therefore when thehandle 13 is applied to the stud the plates 3 and 6 and the blade 1 willbe clamped in position between the end of the handle and the head 12 ofthe stud. It is apparent that by loosening the handle 13 upon the studthe handle may be swung at any desired angle with relation to the planein which the blade 1 lies and when at a desired adjustment may besecured by screwing the handle upon the stud and clamping the parts ashereinbefore indicated.

The handle 13 is provided at that end opposite the end which is providedwith the socket 14 witha sleeve 15 having a slot 16 leading into the.same from one end thereof. A retaining member 17 is adapted to be usedin conjunction with the handle when the same is used for stropping orsharpening the razor blade. One end of the retaining member is adaptedto be slipped endwise upon the sleeve 15 and the said end of the saidmember is provided with lugs 18 which enter the slot 16 whereby themember 17 is restrained against turning movement with relation to thehandle when the parts are connected. The member 17 is hollow and isprovided at its outer end with a longitudinally disposed slot 19.

A blade holder 20 is adapted to be used in conjunction with the member17 and the said blade holder is preferably formed from a sheet of metalwhich posseses. more or less resiliency.

The blade holder 20 is provided with a cylindrical portion 21 adapted tofit in the end portion of the member 17 and the said blade holder 20 isfurther provided with flat portions 22 located at the edges of the clindrical portion 21 and adapted to pass tirou h the slot 19 of theretaining member 17. ne of the flat portions 22 is provided with a slot23 and the other portion 22 is provided with a hump 24.

The razor blade 1 is adapted to be inserted between the portions 22 andwhen the slot 2 of the razor blade is in register with the slot 23 ofone of the portions 22 the hump 24 of the other portion 22 may passthrough the slot 2 of the blade 1 as best illustrated in Fi ure 10 ofthe drawing whereby the bla e is held in position between the flatportions 22 of the holder 20. The holder is theninserted in position inthe end of the retaining member 17 as best shown in Figure.l0 of thedrawing. Therefore the handle 13 and the parts connected therewith maybe easily and conveniently used as means for holding the razor blade 1while the same is being stropped or sharpened.

Having described the invention what is claimed is v A razor comprising ablade havin an oblong transverse opening, blade ho ding members and anintegral spring connection between the blade holding members; sa dmembers by the inherent resiliency of said connection being heldtogether in opposed relation with the razor blade between ture.
